The sleeve orcone is then placed in position and the balls inserted through theopening in the portion 2 and the opening in the ring, and after theballs are all in place the screw isplaced in position and the parts areheld against displacement, but tne ring and sleeve are free formovement.

In addition to the advantages hereinbefore specified the novelconstruction described possesses others which will be readilyappreciated by'those skilled in the art, and while the structuralembodiment of the invention as herein disclosed is what I at the presenttime consider preferable it is evident that the same is subject tochanges, variations, modifications, and departure from the preciseconstruction outlined. I therefore do not wish to be restricted to thedetails of construction before set forth, but reserve the right to makesuch changes, variations, and modifications as come properly within thescope of the protection prayed.

What is claimed as new is 1. A roller stand provided with a ballbearingmounted to automatically adjust said bearing embodying two concentricindependently-movable members with a radial opening through one of saidmembers and means for closing said radial opening.

2. A roller-stand provided with a universal roller and bearing mountedto automatically adjust itself with relation to said roller andembodying two concentric independentlymovable members one of which has aradial opening, and means movably mounted to close said opening.

3. The combination with the roller-stand, of a ring therein, a sleevewithin the ring with a ball-race formed between the ring and sleeve,balls therein, and means for preventing displacement of the balls andallowing independent and universal movement of the ring and sleeve.

4. The combination with the roller-stand, of a ring therein, a sleevewithin the ring, a ball-race being formed in the adjacent walls of thering and sleeve, balls in said ball-race, and means entered from thestand and engaging the ring tohold the parts against displacement.

5. The combination with the roller-stand having an opening with roundedwall, of a ring therein with rounded outer face, a sleeve within thering, balls interposed between the ring and sleeve, and means engagingthe stand, the ring and the sleeve for securing the parts againstdisplacement yet allowing universal movement.

6. The combination with the roller-stand having an opening, of a ringtherein, a sleeve within the ring, interposed balls, and a screw engagedin an opening in the stand and in the ring and having a projection toprevent displacement of the balls.

In witness whereof I have hereunto set my .hand in the presence of twowitnesses.
